I think you have a totally false problem analysis if you think the less than ideal iOS support it the thing why XMPP isn’t as popular as Signal for example.

I never said it was the thing, and you are creating a strawman by implying that I'm expecting it be "as popular as Signal".

What I am saying, plain and simple, is "XMPP might be technically superior in every possible aspect, but this means absolutely jack shit if most if not all of my circles have at 10/20/30% people who will not use it because the client is so feature poor."
